Sequential Retrieval in Dense Associative Memory: Asymptotic Dynamics and Storage Capacity
Mao Mishima, Ayaka Sakata, Kazushi Mimura
We study the retrieval dynamics of an -body asymmetric dense associative memory model, in which sequential retrieval is implemented by shifting one pattern index in the higher-o…
A Reexamination of Noise-Driven Robustness Evolution in Gene Regulatory Networks
Momoko Amemiya, Ayaka Sakata
Gene regulatory network (GRN) models are widely used to investigate gene-expression dynamics in biological systems. In this study, we re-examine an evolutionary GRN model proposed…
Evolutionary Shaping of Low-Dimensional Path Facilitates Robust and Plastic Switching Between Phenotypes
Ayaka Sakata, Kunihiko Kaneko
Biological systems must be robust for stable function against perturbations, but robustness alone is not sufficient. The ability to switch between appropriate states (phenotypes) i…
Prediction Errors for Penalized Regressions based on Generalized Approximate Message Passing
Ayaka Sakata
We discuss the prediction accuracy of assumed statistical models in terms of prediction errors for the generalized linear model and penalized maximum likelihood methods. We derive…
Decision Theoretic Cutoff and ROC Analysis for Bayesian Optimal Group Testing
Ayaka Sakata, Yoshiyuki Kabashima
We study the inference problem in the group testing to identify defective items from the perspective of the decision theory. We introduce Bayesian inference and consider the Bayesi…
Active pooling design in group testing based on Bayesian posterior prediction
Ayaka Sakata
In identifying infected patients in a population, group testing is an effective method to reduce the number of tests and correct the test errors. In the group testing procedure, te…
